Trying to add image to my model. I added in UV editor but it is not showing in render
Just because you assigned the position of the UV in the UV editor doesnt mean the software actually have identified your material.

Think of the UV editor as a guide to place textures and play around how you want it to look.

What you have to do is,


Select texture tab from the properties after selecting the material
Press + button to add a texture node
Scroll down till you see "open" button for texture
(optional) since you had already imported to the texture to the program click the button on the left of the open button. it should list in the items.
Open the texture.
Render again and see the results
